Chương 145: 54. Acclimation 2

Outside the window, the light had started to tilt. The library crowd shifted—the frantic midday researchers thinned out, replaced by the type who intended to stay until closing. The atrium light softened from pure white to something gentler, falling across tables and book spines and glass railings, turning the whole space into the interior of a vast, quietly drifting ship. I finished my last annotation, shoulder already stiff.

Kushima naturally slid the finished textbook out from in front of me and replaced it with a thinner introductory reader.

"That's enough for today," she said.

"Any further and you'll start pretending you're still fine."

"I am still fine."

"Yes." She glanced at me.

"Which is why you've rolled your right shoulder three times in the last ten minutes."

"..." Jess nearly collapsed beside us.

"Help. This isn't tutoring anymore. This is full-spectrum behavioral surveillance." I wanted to argue. But half the energy I would have used for it had already been quietly disarmed by that's enough for today. What was strange was that I didn't feel annoyed. Before—if someone called a stop while I was still trying to push through, I'd have found it intrusive, controlling, the kind of thing that made you want to tell someone to mind their own business.

But now, maybe because the forest assessment had already burned off a layer of whatever unnecessary pride I'd been carrying, or maybe because she'd spent the entire afternoon walking exactly the line between infuriating and actually useful— I just made a short sound, capped my pen, and said:"Let's go." Kushima nodded and started packing. I followed. Halfway through, I noticed something: we were packing at the same pace.

Even the order—which draft pages went inside which book, which book went on top—had become automatic. Like it had been rehearsed.... That was the most alarming thing of all. Jess picked up her bag and delivered her closing remarks standing:"Today's summary: Shimo is alive, the textbooks are alive, Kushima's domestication progress is stable, and I as an observer am deeply gratified."

"One more word and I'm confiscating every drink in that bag."

"What? There's one in there that was supposed to be yours."

"Not anymore."

"You're ruthless, Shimo."

"Mutual." We walked out together. Evening stretched our shadows long across the library floor, nearly liquid. Still plenty of people, footsteps and voices and the scrape of pushed-back chairs all layered together—but somehow not noisy. Kushima walked on my left, carrying half my textbooks as if that were simply what you did. Jess walked on my right, drinking her soda and delivering an extended, merciless commentary on today's tutoring observation report. I should have been annoyed.

But when we stepped through the library's glass doors, the first thing I felt wasn't exhaustion, and it wasn't the stomach-drop of three months from now I might be on the Yukikaze heading to the front line. It was something worse. More inconvenient. The quiet realization that I'd apparently started to find this normal. Someone carrying half my books. Someone making noise beside me. Me in the middle, walking back to the dorm between them.

Normal enough that if one of them were missing someday, I'd probably feel the absence before I understood why.... Damn. That was exactly the kind of thing I shouldn't be getting used to. The next morning, I woke up with an unsettling sense of déjà vu. For good reason. The first second: Jess on the opposite bunk, aggressively complaining through a toothbrush about how the scrambled eggs at breakfast looked like a failed construction experiment.

The second second: Kushima standing at the side of my bed, holding Foundations of Fleet Management—the one I'd been reading last night before falling asleep with it on my chest—speaking with the calm of someone delivering a combat zone weather report.

"Shimo, get up. The sticky note you put on page thirty-seven fell out. I put it back." Half my face was still in the pillow. My brain stalled for two seconds.... Wait. Shimo?

"Shimo, move." Jess appeared at the bathroom doorway, toothbrush hanging from her mouth, muffled but efficient.

"Don't you have Fleet Management Overview first period? Stay in bed any longer and you'll be the first person in history to sleep through the supplementary course she was assigned supplementary work to prepare for. Personally I find that hilarious. I support it." I sat up, hair in full disaster mode, first reaction not to yell at anyone but just to look at them both. Kushima, holding the book, wearing the expression of I understand you're not fully booted up yet, but please don't waste time.

Jess, foamy at the mouth, grinning like she was waiting for my brain to publicly short-circuit. And then a very alarming thought surfaced. When exactly did they start calling me Shimo? Not Hoshino. Not hey. Not captain or you. Shimo.

And not the sticky, deliberately familiar kind—the kind that had already evolved past that, so natural it felt like my name had always been this, no pause, no performance, as if the line between regular roommate and person who just calls you that had been quietly stepped over while I was looking somewhere else. Was it the forest assessment? After the barbecue?

Or earlier—early enough that I hadn't had the bandwidth to track it, because back then we were all either busy surviving or busy pretending we were fine, and nobody was going to stop and note hey, when did you start calling me that, because that was the kind of detail that only existed in the kind of story I refused to be living.... Whatever. Let it go.

Being alive was already exhausting enough without writing a formal report on the evolutionary history of how people addressed me and submitting it to the Student Council.

"Shimo?" Kushima called again, this time closer, and set my uniform jacket on the foot of the bed.... Great. She didn't think anything was wrong. What was worse: I was starting to not think anything was wrong either.

"I'm up." I dragged a hand through my hair and grabbed the book as I got out of bed.

"The two of you flanking me first thing in the morning—I'm starting to think I don't live in a dorm, I live in a detention facility."

"Detention facilities don't put your sticky notes back," Jess said, rinsing and spitting with serene indifference.

"Or bring you lunch," Kushima added. I pulled on my jacket and thought, with genuine sincerity, that this dorm had evolved into a highly suspicious triangulated monitoring system, and I was the humanoid test subject with nominal autonomy whose daily habits were under continuous observation. But fine. At least both monitoring units were currently on my side. Morning classes were as inhumane as ever.

Military academy mornings always carried a specific malice—the kind that wanted to squeeze your brain into a barcode and stick it back on your forehead. First period: Combat Zone Formation Overview. Second period: Fleet Operations Guidance. Third period: the worst kind—the instructor who lectured with the quiet implication of I'm perfectly calm, but if you fall behind, that's your problem.

I'd thought that after spending half of yesterday afternoon with Kushima walking me through the material, today might at least be slightly breathable. The academy, predictably, disagreed. It had let me learn to swim yesterday. Today it kicked me into a deeper pool. By the end of the morning block, half my brain had entered do not disturb, internal reconstruction in progress mode.

When the teaching assistant handed out new materials, I looked at the stack of correctly formatted, precisely titled books—each one clearly designed to shave three years off a first-year's life—and felt a very principled groan from somewhere in my stomach. Around me, chairs scraped. The cafeteria crowd had started moving. The air carried the collective anxiety of if we don't queue now, we're eating leftovers. I looked at the new textbooks.

Support creative writers by reading their stories on Royal Road, not stolen versions. Looked at my watch. Lunch. Then I did something that was obviously terrible for my physical and mental health—I didn't head to the cafeteria. Instead, I sat right back down with my textbooks. Just flip through two pages. Just two. Check the structure. Really, just a quick look. That kind of reasoning has about the same credibility as "I'm only going to take one sip of Coke today." It's usually just lying to yourself.

I'd barely made it to the table of contents when someone set a water bottle on the corner of my desk.

"I knew you wouldn't go." I looked up. Maki was standing beside me, holding a meal box in one hand and her notebook in the other, wearing that perfectly calm expression of someone whose prediction had just been validated with clockwork precision. Jess was half a step behind her, cradling a bag of bread she'd apparently sourced from somewhere, looking as pleased as a bookie who'd shown up personally to collect on a winning bet.

"Wow." Jess stared at the open book spread across my desk and drew a theatrical breath.

"Shimo, you've evolved to the point where you can skip lunch entirely? Is this what they call academic passion? Or is it passion for a certain study partner?"

"Shut up now and I'll consider sharing a page of notes with you," I said.

"No thanks, notes aren't edible." She dropped into the empty seat in front of me and planted the bread bag on the desk.

"Besides, I'd rather watch you get called on in class later and suddenly realize you actually retained something from yesterday afternoon. That expression will be more satisfying than lunch." Maki ignored her and pushed one of the meal boxes directly in front of me.

"Eat first. Then read," she said.

"I'm not hungry yet."

"That line has about the same credibility as yesterday's 'I'm just going to flip through a few pages,'" Jess pointed out. I was about to argue, but Maki had already smoothly pulled the textbook toward herself, glanced at the cover, and flipped to a specific chapter.

"Save this for the afternoon. Start with the fleet rotation and supply prioritization the instructor mentioned this morning." She opened her own notebook as she spoke, her finger stopping at the page we'd marked yesterday.

"If he cold-calls today or tomorrow, odds are he'll start here."

"How do you know?"

"Because he likes to rattle people once, then check survival rates starting from exactly the section most likely to kill first-years." Her tone was perfectly even.

"Also—" She paused and showed me a page of lecture notes from previous years.

"He has a pattern when he asks questions," she said.

"Starts with concepts, then suddenly shifts the scenario to a concrete mission to see if you can do more than recite definitions." I looked at that page, then at her.

"You actually have this kind of stuff?"

"Better to be prepared," she said. Jess looked deeply moved.

"Kushima, you really are the type who would start stockpiling water, medicine, and generators three months before the apocalypse."

"Wrong." I looked down and started opening the meal box, adding coldly, "She's more the type who, before the apocalypse even starts, has already mapped your escape routes, rationed your food supply, and formatted your will." Maki glanced at me and actually nodded.

"More efficient that way." … Right. I take it back. She doesn't just resemble that type. She is that type. Anyway, lunch ended up in my hands. Nothing romantic about it—no soft-lit school drama bento moment, just practical food that wouldn't interfere with reading. And that was exactly the problem. The more ordinary it was, the more annoying it became.

Because ordinary meant she wasn't performing kindness; she'd simply filed "Shimo forgets to eat when focused" under objective fact and started engineering countermeasures. I ate while silently condemning this quiet invasion of my personal boundaries. And kept accepting it anyway. … Humans really are weak. The afternoon Fleet Management class was taught by an instructor named Brenner.

He was a military academy specialty: somewhere around fifty, uniform looking like it had been extruded directly from the regulations manual, posture more textbook-correct than the actual curriculum, never raising his voice—yet you sat there with the persistent sense that if you nodded off, he might pin you to the blackboard with a piece of chalk. When he walked in, the air pressure across the entire room seemed to drop a register.

"Chapter Six. Correlation between fleet supply chains and operational tempo." He set his textbook on the lectern and cut straight to it—no preamble, no pleasantries.

"No flowcharts today. You should have covered the basic framework yesterday. Since you have, I'll ask directly." Great. Here we go. I straightened almost reflexively, and the three lines Maki had written in the library yesterday floated up automatically— Who's moving. What keeps them moving. Who decides where they move. Brenner swept the room, his gaze sliding across each face like a searchlight before settling on the simulation diagram at the front.

"Scenario: A reduced-strength escort fleet is en route to a frontline sector." He picked up his pointer and tapped several light points on the projection.

"En route, the fleet receives new orders demanding accelerated entry into the combat zone. However, supply nodes along the route are incomplete, the crew rotation just came off a high-intensity alert cycle, and medical and maintenance personnel are understaffed. In this situation—" He paused for a second, eyes scanning the room.

"What is the first thing command needs to determine? Not 'can the fleet continue to advance'—what is it?" The classroom went quiet. That's the most irritating thing about questions like this. On the surface it sounds like one sentence. What it's actually doing is checking whether you've wired the whole system together in your head. A second-year in the front row raised her hand first, giving the textbook answer: "Assess sustainable combat duration and remaining supply margins." Brenner nodded once.

Not right, not wrong. Someone else added: "Confirm the priority level of frontline orders relative to escort target mission classification." Another nod. Then his gaze suddenly swung to the back row.

"Hoshino." I almost reflexively said "What do you want," and managed to strangle that impulse at the last second—that was exactly the kind of thing a trouble student would say. The entire class turned. I could feel Jess settling into full spectator mode behind me to the left. Maki hadn't turned her head, but her pen had stopped moving. A very brief pause—so brief no one else would have noticed. Brenner looked at me, tone flat.

"You answer." Perfect. Crammed yesterday, autopsy today. The academy really runs on efficient scheduling. I took a breath, glanced at the open page, and dragged back that "translate to human language first" approach from yesterday.

"It's not about whether the ships can still move," I said, my voice coming out steadier than expected.

"It's about figuring out… which elements in this fleet can't all fail at the same time." Brenner didn't cut me off. The three lines Maki had drawn flashed through my head. I kept going.

"Personnel, supplies, orders. If the rotation just came off high-intensity alert, personnel readiness is probably the first thing to break. Incomplete supply nodes means the logistics rhythm is already unstable. Insufficient medical and maintenance staff means even if you push forward now, one more incident down the line and the fleet's entire sustainment capability drops off a cliff." The room was quiet. Not the "no one's answering" kind of quiet.

The "people are listening to see if you can actually finish this" kind. I licked my slightly dry lips and continued.

"So the first thing to determine isn't whether any individual ship can still run. It's… whether the command chain can still hold the fleet's tempo together. Put simply—who can still move, what they're running on, and whose orders people are actually still following." The moment that last line landed, I could feel several heads in the room lift almost imperceptibly. Because that wasn't textbook language anymore. That was the rough translation—the version that smelled like actual field use.

Brenner looked at me for two seconds.

"Continue." …Oh. That meant I hadn't screwed it up. The wire that had been pulled taut in my chest finally loosened, just slightly.

"If orders are demanding accelerated entry into the combat zone, that means high command has timing requirements for the front," I said.

"But if supply nodes and crew rotation can't sustain that tempo, following the order as given might burn out the escort fleet before it even reaches the combat zone. At that point you're not delivering a fighting force—you're just shipping metal that could still move to become metal that can't." Someone in the back row laughed quietly. Brenner didn't smile, but he didn't shut it down either. I finished the thought.

"So the first thing to determine is—how does this order get executed without the fleet losing its capacity to carry it out before it arrives." This time, Brenner nodded definitively. Not the polite kind. A clear, specific nod—the kind that confirmed a student hadn't made it this far on pure luck.

"Not bad," he said. A military academy instructor's "not bad" is basically equivalent to "very good" in the civilian world. From a teacher who actually spoke like a human being, it might even translate to "this answer has a brain behind it." I sat back down. My palms, catching up belatedly, had gone warm. Someone beside me was writing something at the bottom of a notebook page, then nudged it slightly my way. I glanced down. Very neat, very Maki Kushima handwriting. Not luck. Just four characters.

No smiley face, no exclamation point, no additional commentary. For some reason, those four quiet words pressed harder into my chest than Brenner's "not bad" had. … Damn it. She really has been picking her moments lately. I pulled the notebook page toward me, pretending to review the course summary, mostly to hide the corner of my mouth that nearly slipped. Up at the lectern, Brenner had already moved on.

"Good. Since someone brought up frontline tempo, let's push one step further." His pointer shifted to another diagram.

"If this escort fleet's destination is the outer perimeter of Orion Alpha, and the escort mission requires rendezvous before the main fleet completes redeployment—then the choice of escort vessel types and supply load distribution directly affects what?" My spine went slightly rigid. Orion Alpha. To everyone else in the room, it was probably just a case study location. I knew it wasn't.

That was the place Aki Kushima had named herself, sitting in the Student Council office with that smile perfectly suited for selling someone out and then handing them a handkerchief. And now Brenner was using it as a classroom example. The feeling was strange. Like catching a glimpse of an exam cover you weren't supposed to see, then the next day the instructor starts working through those exact questions as practice problems.

You know it doesn't necessarily mean anything, but you can't quite convince yourself it's pure coincidence. Especially when his next line was:"Under a standard Federation destroyer configuration—if the fleet contains a unit required to handle escort duties, communications relay, and high-speed disengagement capability simultaneously—what is the one thing that unit can least afford to lose?" Destroyer. The name surfaced in my head almost reflexively. Yukikaze. Not because I actually knew what it looked like.

But because those three characters had already been lodged in my brain like a very fine needle—placed there in advance by someone, sitting quietly most of the time, starting to sting the moment anything related came near. Brenner didn't call on me again, but every line of his analysis felt like he was slowly sketching the outline of a ship I hadn't actually seen yet. A destroyer isn't a capital ship. But it's usually the first unit asked to step up and take the hit.

Fast, agile, capable of escort, relay, cover—which also makes it the easiest target for the brass to casually slot into every task that comes with the assumption of "you can handle it." And once frontline tempo accelerates, supply nodes fragment, and the escort target demands punctuality—that kind of ship becomes the perfect consumable, thrown in to hold the situation together. Listening to him, I suddenly understood what Maki had said yesterday. Learn to read how a ship dies first.

Because most ships don't die from one direct hit. They die from being asked to do a little more, hold on a little longer, push the tempo just one notch faster, cut one more crew rotation, stretch one more resupply cycle—until finally, under some perfectly reasonable order, they quietly break. Quietly enough that the system never seems to consider whether it was capable of pain. When the bell rang, I realized I hadn't lost focus once the entire period.

Not because I'd suddenly developed a passion for fleet management. But because that low, unpleasant instinct—the one that had started as a single sentence in the Student Council office yesterday—had slowly grown into something with clearer definition. Yukikaze wasn't just a name anymore. Orion Alpha wasn't just a textbook coordinate. They were starting to have structure, weight, and the faint premonition that one day they were going to come down directly on top of me.

As I packed up my textbooks, Maki, same as yesterday, smoothly took two of them first. Jess kicked my chair leg from behind, dropping her voice to a laugh.

"Not bad, Shimo. Emergency tutoring in the library yesterday, fielding the instructor's questions today. You should write a reflection paper: 'On the Measurable Academic Outcomes of Being Forcibly Abducted into the Kushima Family Study Program.'" I turned and glared at her.

"The first line of that paper would be: 'The subject did not consent to participate in this study.'" Jess laughed hard enough that her shoulders shook. Maki, standing beside me with the two books already in her arms, added quietly:"But the results were good." I looked at her. Her expression was perfectly ordinary, like she was simply stating a fact. Which was somehow exactly why I couldn't figure out what to say back. In the end I could only sling my bag onto my shoulder and mutter stiffly:"…

That's because I already had the foundation."

"Mm." Maki nodded.

"Plus a little correct guidance." Jess actually burst out laughing.

"I'm sorry, but the two of you doing this 'I refuse to admit anything' versus 'calmly taking credit' routine—you genuinely sound like an old married couple arguing over whose soup turned out better."

"Shut up," Maki and I said at exactly the same time. … Great. Several people in the class turned to look. I sincerely believed that at this rate, I wasn't going to die on the front lines. I was going to die under Jess McCallow's mouth first. But walking out of the classroom and down the corridor toward the next period, I admitted something to myself without any particular dignity. That afternoon yesterday had genuinely saved me. And what was worse—it wasn't just the studying I was getting used to anymore.

I was getting used to the fact that in places like this, places I was supposed to grind through alone, I could look back and find those two still there beside me. That kind of habit is dangerous. But for now, for some reason, I wasn't ready to break it.
